In December 2011, Microsoft held an event in San Francisco to demonstrate Windows Store, through which all Metro style Windows 8 apps will be sold. At the end of the event, Microsoft announced that the public beta will be released sometime in February 2012, along with the Windows Store Beta. However, a few screenshots from a pre-beta build were leaked. New features included an updated setup preparation, a new theme, Aero Lite, a new background on the start screen, and new metro-style apps like Reader, Music, Video, and Photos.
